These are the Attributes I focus most closely on, when trying to Evaluate the Prospects of HalfBack Prospects:

Processing Speed ~ How Rapidly & Effectively they Read & React to the rapidly changing LandScape in front'f'mPower ~ How forcefully they Run the BallAcceleration ~ I don't give a Rat's Ass about "40" Time. How Quickly do they Hit The Hole & Turn the Corner?Fluidity ~ How Serpentine he flows through Traffic.Ricochet ~ How Explosively they Burst out'f their Breaks when they Change DirectionsSecurity ~ How reliably he holds onto the PigSkinPass Blocking ~ Can they stay on the field without endangering their QuarterBack's Life?Pass Receiving ~ Are they a true Dual Threat ~ what I call a FlexBack?

I think that deploying a Feature Back is a ridiculously stupid way to go: You'll get much better results if your HalfBacks aren't constantly battered and bruised. It's the most punishing Position in the entire Game, as evidenced by the notoriously short Shelf Lives of HalfBacks ~ especially Feature Backs.

As such, it makes no sense to me to have less than 3 reasonably capable HalfBacks to share the Load.

After all: That's about400-500 Tackles they need to absorb, each Year.

Nobody's asking any "Wide Receivers" to absorb 400 Tackles a Year, last I checked!!

And most of those are at the hands of 200 Pound CornerBacks, not 300 Pound Gorillas!!

And as it's quite obviously best for the Team to split up the Carries, it stands to reason that most HalfBacks simply don't warrant 1st Round Investments...with some few notable exceptions!!

I'm a big Fan of Zachary Stacy. He's a Strong, Quick, Decisive One Cut Runner who Hits The Hole Hard, knocks people down, tears up Yardage, and consistently Moves The Chains. He reads the Field extraordinarily quickly and extraordinarily well, he's Patient, he's Smart, and takes very few Losses as he leads your Team DownField.

Furthermore, I believe that there is untapped athletic Potential, here, as his Short Shuttle & 3 Cone Times at the Combine suggested far more explosiveness lies within than we've seen on Film.

But even if he never translates that onto the Field to a greater degree than he already has, Zac Stacy strikes me as an extraordinarily impressive HalfBack.
